These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values are with respect to the anode terminal. 2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions MIN MAX UNIT VZ Regulator voltage Vref 30 V IZ Regulator current 2 100 mA TA Operating free-air temperature range TL430C 0 70 °C electrical characteristics over recommended operating conditions, TA = 25°C (unless otherwise noted) PARAMETER TEST TEST CONDITIONS TL430C UNIT PARAMETER TEST FIGURE TEST CONDITIONS MIN TYP MAX UNIT VI(ref) Reference input voltage 1 VZ = VI(ref), IZ = 10 mA 2.5 2.75 3 V αVI(ref) Temperature coefficient of reference input voltage 1 VZ = VI(ref), TA = 0°C to 70°C IZ = 10 mA, 120 ppm/ °C II(ref) Reference input current 2 IZ = 10 mA, R2 = ∞ R1 = 10 k Ω, 3 10 µA IZK Regulator current near lower knee of regulation range 1 VZ = VI(ref) 0.5 2 mA IZK Regulator current at maximum 1 VZ = VI(ref) 50 mA IZK Regulator current at maximum limit of regulation range 2 VZ = 5 V to 30 V, See Note 4 100 mA rz Differential regulator resistance (see Note 5) 1 VZ = VI(ref), ∆IZ = (52 − 2) mA 1.5 3 Ω VZ = 3 V 50 Vn Noise voltage 2 f = 0.1 Hz to 10 Hz VZ = 12 V 200 µV Vn Noise voltage 2 f = 0.1 Hz to 10 Hz VZ = 30 V 650 µV NOTES: 4.
